h264enc for Linux

[microchip8]

Have you already tried the two xbox presets available (mx and mxhq) ? They don't work? I don't see anything special in the above settings that'll make the already present xbox presets in the script incompatible. The only thing is that CABAC is disabled while I have it enabled in the xbox presets. Maybe xbox1 can't take CABAC?

[mrplow]

Those are xbox360 presets and to tell you the truth I tried them many revisions ago and many xbmc revisions ago and at the time it would stutter from time to time in high action scenes. But that was a while ago and I could try them again this weekend.
It seems the xbox1 can only handle CABAC if Deblocking is disabled and visa versa. With CABAC on and deblocking off the video is better quality but larger and with CABAC off and deblocking on the quality goes down slightly along with the file size.

[microchip8]

hmm, CABAC is supposed to increase compression more than CAVLC so I'm a bit at a loss why you get smaller file sizes when you disable it. If I add such a preset, then I'll only disable CABAC but leave deblocking on. Can you try the xbox presets again on a short sample and see if you still get problems with them on the xbox1?

Hi,

I have a multi core cpu I was wondering if there is an option I need to be setting to make the encode multi-threaded? I got h264enc off the Karmic repository today (version 9.0.0) and am trying out a test encode but it is currently only using a single core. A quick search of this thread and the man pages hasn't revealed anything to me ... :-(

Thanks in advance.

First of all, I'd recommend getting MPlayer/MEncoder SVN, built against a recent libx264 version and then the latest h264enc version. Ubuntu provides oldish versions of these programs.

Multithreading should work with those versions too, but maybe froggy1 can guess what's going on.

[microchip8]

the threads=auto option is always used in h264enc so it should work. As nm said, get latest stuff from SVN/git/whatever

[daniel.pool]

Froggy1, nm,

Thanks for the really fast reply guys.

I've got the latest x264 from git, but I'm currently unable to get the latest mplayer from svn, one of the dependencies (I'm using this (http://ubuntuforums.org/showthread.php?t=1305181) guide on compiling mplayer-nogui, so maybe I'm building completely the wrong thing) has a broken deb. I've got a bug raised against it, so for now the only way I've been able to get h264enc working is to go with what is coming from rvm's ppa (https://launchpad.net/~rvm/+archive/testing).

I'll try upgrading as soon as a fix is made available for the deb (or someone points out I'm being thick and get pointed to the right guide for compiling on Karmic :))

[microchip8]

what is this broken dependency? Just go to mplayer's site, get SVN link, and pull from there. That's what I always to (though I have a script called getprog which accepts params about which software to pull from SVN, something small I've written to east it for me)

[daniel.pool]

what is this broken dependency?

To quote Andrew (http://ubuntuforums.org/showthread.php?t=1024592) from the Ubuntu forums: By default Ubuntu does not offer a particularly rich development environment so we need to download the required 'dev' files which are specific to Intrepid Ibex. (These files are loosely modelled on the results of the command 'sudo apt-get build-dep mplayer-nogui', I have removed some files and added others.)

The dep that was failing me was libopencore-amrnb0, as stated, there is a bug (https://bugs.launchpad.net/ubuntu/+source/opencore-amr/+bug/454026) raised against it.

However, as it turns out in researching these links to reply to you (and running the apt-get command again to try and get the error), the dependencies now actually install, which means my compilation should succeed! Huzzah.

So, I'll grab the latest h264enc once I've got the latest mplayer. Will update this with my results. Thanks very much for your help.

Thanks
~Dan

[microchip8]

This is why I don't use Ubuntu! They got to have the most incompetent packagers out there :P
I'm a packager myself but luckily not for Ubuntu...

So then... compile everything, first x264 then mplayer, and see if you get threading problems. Make sure to run h264enc -r to reset its config file

[daniel.pool]

Gaah, it's still only running on a single core :mad:

I'm pretty sure that it's not an option I've selected (I've attached my options file just to make sure).

I'm going to call it a day on this, but will look at it again tomorrow evening. I'm guessing the best way would be to call the encoder directly from the command line and see what is happening there. Is it mencoder called, or ffmpeg?

Cheers,

[microchip8]

better post attachments to an external site as it can take here some time before they get accepted by a mod
as for the threading. I don't have problems, neither other users who have reported that it works

[kripz]

Im getting errors after updating h264enc, mencoder, mplayer and ffmpeg.

@kripz

Look at the top, your libx264 is not new enough as it's missing weightp option. Pull latest x264 from git and compile it, then you may need to recompile mplayer and make sure it's linked to it, not to another older libx264 if you have one on your system

[WalterK]

yeah folks dont forget to keep x264 updated as well as mencoder and mplayer.

[kripz]

lol i totally missed that line

edit: those patches on your website are very outdated?

[microchip8]

For NAL-HRD, you need to use a preset which has vbv-bufsize and vbv-maxrate set. The blu-ray/avchd presets have these. Unless you really need HRD signaling, you shouldn't use it otherwise. Also, the HRD patches are still (very) experimental

For the audio issue, it's a known problem in the default demuxer for TS files. Configure as usual, save all to the batch file, open it up and add to the mencoder line -demuxer lavf then run your encode from the batchfile. See if this fixes it for you

[kripz]

Ok, ill try that next time.

I'm now having another problem with another movie, not sure what it is. I didnt save the mencoder options but here they are from within the job folder.

I've never seen it drop down to those speeds before. This was after compiling and updating most of the required programs although its a new Bluray that i got.

Also, instead of defaulting the jobs to the home directory, can you please make it specifiable? my home directory isnt very big.

[microchip8]

did you compile x264 with asm? yasm enabled?

for the job directory, you can already do that in the config file. Look at the TEMPDIR variable in /home/username/.h264enc/config and set it there

[microchip8]

Just came back from the pub ;)
Looking again at your settings, no wonder you'll get such slow speeds (even on Quad cores). You got 10 frame references, 7 bframes with badapt=2, subq of 10, trellis of 2, me_range of 64, weigthp=2, mbtree on, me=tesa and lookahead of 60. This combined with a resolution of 1920x1080 will be pretty slow, even on quad cores and some of the settings are placebo-like (me=tesa f.ex). I bet you're using the insane high quality preset, huh? This preset is a "troll" preset, for those who think they'll see the difference between it and the EHQ preset, and of course for the Japs who love crazy settings ;)

My advice: do not go above the EHQ preset. I always use VHQ but only because my system is a bit slow. Nevertheless, it produces very nice results

[kripz]

Ah yep, i wanted to try a new setting. baited:devil:

did you compile x264 with asm? yasm enabled?
Well all i did was configure and make. no special options. Will those 2 enable better performance? Google doesnt have much regarding this, ill have to search around here for all the switches that will enable higher performance.

[microchip8]

If you haven't done so, recompile x264 with asm support by installing yasm. Without asm enabled, x264 will be DOG SLOW ;)

so after installing yasm, just do ./configure --enable-shared && make && sudo make install

[kripz]

Done. I had an idea for this program, perhaps consider adding an option to send an email once conversion is done (as i run this on a headless box).

Would something like this do as i described?

if [ -f "$BATCH" ]; then
cp -f $BATCH $HOME
source $BATCH
echo ""
brown "-> Have a nice day ^_^"
echo ""
echo "Converting blah completed `date`" | mail blah@blah.com -s "h264enc conversion complete"
rmconf
else

[microchip8]

Yes, but you need a working/configured smtp running on the machine you're executing the h264enc script. So you should tell it to use an external smtp server (like that of your isp) ;)

[microchip8]

ChangeLog for version 9.1.1
* Disabled weightp for the AppleTV presets
* Added new option sliced_threads present in latest x264 from git
* Enabled b_pyramid for some presets that use mbtree as it now works with mbtree
* Updated the preset.cfg file. Added sliced_threads option
* Changed all video ALLOW_* variables in the config file to ALLOW_VID_*
* When using dd to dump a DVD to an ISO, use options noerror,sync and a bs size of 2048
* Added support for sending mails. This requires the 'mailx' program and a valid .mailrc file in the home directory.
Mail notification can be enabled in the config file of h264enc which also offers an example of a gmail setting for .mailrc
* Bumped config file version to 13
* Updated copyright dates

[microchip8]

ChangeLog for version 9.1.2
* Fixed a severe bug that can cause in some cases severe data loss when using a custom temp directory.
It manifests itself when using a 'top' directory as custom temp directory such as a partition mount point or even
the user's home directory. In such cases, the top directory will be deleted upon script termination or when encoding
finishes, resulting in possible massive data loss due to rm -rf $TEMPDIR if TEMPDIR was set to, for example, /home/username
or points to a mount point or another directory that may be important to the user.
From now on, always use a job<pid> directory inside the one set in the TEMPDIR variable so it'll only delete the job<pid>
directory and not its parent one, minimizing possibility of a data loss disaster
* Set nomixed_refs for the iphq/iphhq presets

[kripz]

Does h264enc support decoding of a single DTS + AC3 audio stream?

[microchip8]

Yes, but only for DVDs at the moment. Also DTS is a bit problematic as I always get skipped frames and haven't looked much on how to fix it. For file encodings, only 1 audio track is supported but if you export the settings to the batchfile, you can modify it for two tracks and encode from there

[Redsandro]

Wow this is so nice, thanks!

I have one issue I'm wondering about. Pretty much always when I convert a random batch of television shows to a 320x240 mp4 using the symbian60 preset and all defaults (except for resolution), right at the start there's a bunch of random SKIPPING FRAME messages. About 5 or so. That causes a loss of AV sync. Any idea why this happens?

[microchip8]

No idea really, but a few skipped frames at the beginning shouldn't cause any noticeable A/V sync issues, and mencoder most of the time compensates as it adjusts its a/v sync due to this

[Redsandro]

Wow.. what? Who?

[nm]

Looks like someone's testing a chatterbot.

Hi,

I've got the problem that MEncoder is exiting with this message:
-a52drc is not an MEncoder option

[microchip8]

Hi,

I've got the problem that MEncoder is exiting with this message:
-a52drc is not an MEncoder option

I guess they removed dynamic range compression control. I'll have to see if they have replaced that option with something else or just removed it and then update script accordingly :)

[microchip8]

@elektronaut

Alright, I looked around and it seems latest mplayer from svn needs external liba52 library. If it's not detected during configure, then the -a52drc option will be disabled. However, there's a --enable-liba52-internal option in configure which enables mplayer's internal liba52 if one doesn't have or want to link against an external liba52. I've no idea why the mplayer devs have chosen to disable completely liba52 if an external liba52 is not detected instead of enabling the internal one. Maybe it's a bug in configure, no idea.

The -a52drc option is still present in cfg-common-opts.h... so either install external liba52 lib, or configure with --enable-liba52-internal and compile again.

EDIT: seems according to a guy in #mplayerdev that there was a commit which disables internal liba52 because libavcodec supports it. It also said that if no one objects, internal liba52 will be removed in a few months.... so I'm thinking of removing the -a52drc option in h264enc (it's not mandatory and one can do without DRC control anyways)

[microchip8]

ChangeLog for version 9.1.3
* Made the TEMPDIR variable escape spaces in directory names
* Small update to the mkvtags_func() function
* Removed the -a52drc option for AC3 encoding
* Added new x264 intra_refresh option to the script and the preset.cfg file
* Added two new variables, DVD_DEVICE and CDROM_DEVICE, to the config file where user can set a default block
device to encode from. This updates the config file to version 14
* Merged the get_dvd_devices_func() and get_vcd_devices_func() functions into a new one called get_devices_func()

Nice!

Any idea why MEncoder skips so many frames? ~6 frames on every video I encode for my phone, always within the first 2 seconds , just enough to make every action movie gunshot explosion badly annoying. :P

I've no idea.... does the skipping continue throughout the whole encode or does it only occur at the beginning and for a very short period? What are your encoding settings (save to batchfile & post here). Did you force a specific framerate? Can you post a sample of the original?

[Redsandro]

It comes only at the beginning, usually within two seconds.

I am converting old shows to run on my Symbian phone from DVD colletions I have that were recorded in 4:3 aspect ratio because they fit nicely on my phone screen. Such as X-files and Friends. I use downloaded rips of these seasons because I use my headless server to do the encoding and it takes about 2 days for a season and I am too lazy to figure out how to use DVD's and swap them all the time.

But although downloading rips for private use of video you own is legal where I live (Netherlands), uploading is not and would violate rule 6 here.

[microchip8]

Well, this is not unusual for the first few frames to get skipped so that mencoder can adjust its A/V synchronization. It may become a problem if this continues throughout the whole encoding. When I encode DVDs, I also get at the very beginning a few frames skipped but the rest is fine. Do you get any problems with these few skipped frames at the beginning? If not, then ignore them. If yes, you can completely disable mencoder's sync by adding to its arguments -mc 0 but beware that this can cause a lot more problems that it can solve. Other than that, unless I have a sample of the original you try to encode, I can't do much. The above settings look fine to me

PS: uploading a sample of the original you own is not considered a rule 6 violation on this forum. Many people upload samples to help out development or troubleshoot problems ;)

[Redsandro]

Oh so it's sort of synchronization compensation! Well during speech I hardly notice it, but when shots are fired I can clearly see it's off. So I thought it was some error that introduced 0.2 seconds of audio-lack-behind.
But how can MEncoder think there's a sync issue when it has no ears? The source is good.

I thought I'd give you a sample then, for educational fair use purposes and stuff, but I cannot quickly find an example where a machine gun is fired (because then you could easily see the sync problem) and I need to go to work. In stead I found a single gunshot but with a keen eye you can clearly see a ~0.2 sec sync issue and you'd have to trust me that in some cases it will be more annoying than it looks. :)

The original, correct sync: (6 second snippet)
http://red.chillosophy.nl/trash/xfile0124/x0124orig.avi

The mp4 s60 encode, audio comes later because 6 frames are missing from the start (not included) (6 second snippet)
http://red.chillosophy.nl/trash/xfile0124/x0124s60.mp4

Here's a snip from the start of the original, because the missing frames on encodes always occur at the start: (9 second snippet)
http://red.chillosophy.nl/trash/xfile0124/x0124start.avi

[microchip8]

Mencoder doesn't need ears to adjust a/v sync ;) it has an internal algorithm to do this (though it's not perfect, but then what is?). I watched the mp4 (audio is a bit out of sync in the mp4 while playing under mplayer but the mp4 is not directly coming from h264enc - you used avidemux and I've no idea how it deals with sync) and the other two avi files, but I cannot spot any sync issues, though I must note that mine ears are not that fine-tuned ;)

As for what you can do, you may need to play around with -delay and/or -mc options of mencoder. Currently, h264enc doesn't support (yet) any way of adjusting these options

A/V sync is identical in these clips when played back with MPlayer or VLC. I also tried changing the sync by 0.2 seconds (to both directions) in the other file and then there was a difference. Which players have you tried?

[Redsandro]

Yes I used AviDemux to cut a snip out of my full encode. I used copy stream (it snaps to keyframes) and I thought it made an identical copy like that.
Thanks for the advise though. I might want to try -mc 0 on my next batch.

A/V sync is not identical here when using:
MPC (win)
MPC-HC (win) (I think that one uses ffdshow internally, not sure)
VLC (win)
RealPlayer (I know! But it comes with Symbian S60 and for once it's pretty good at it. :P)

Note that you need an accurate observational A/V sync internally if you know what I mean. It's only a small difference.

I am sorry I did not try linux players because I use my server with ssh for cool stuff like h264enc but for anything other than text I use my windows machine.

Well, I controlled my test by changing the sync, in which case I could hear a difference between the samples, but originally I didn't notice any difference. Did you try these sample clips in all those players too? Maybe they are different from your full encodes.

[Redsandro]

Yes I tried the samples before I uploaded and just now I tried them in VLC. I do notice the difference or I am really getting crazy. Maybe it's not 200ms because that was just a 6 frame guess. A wrong guess btw, 6 frames would be about 250ms in this case.

I watch sometimes when I need to travel by train to work, school or friends. When I come across a more obvious example I will post another example.

ChangeLog for version 9.1.4
* Set default H.264 level to 'auto' and also accept integer numbers as levels in addition to accepting fixed point ones,
ie both 41 and 4.1 are now accepted as valid levels
* Renamed the rmconf() function to rmtemp()
* Moved creation of temp dir, the interrupt_func() and rmtemp() functions at the beginning of the script
* Fixed a bug in the DVD part of the -scan option where lsdvd doesn't get a valid device passed. Bug was introduced due to
changes in the new get_devices_func() function
* Reduced duplication in the mencoder_opts() function
* Various small code improvements

[microchip8]

ChangeLog for version 9.1.5
* Reduced duplication in the audio encode exporting code by moving it inside functions
* Reduced duplication in the MKV/MP4/TS/OGM exporting code by moving it inside functions
* Reduced duplication in the code that prints some information before encoding starts
* Various minor code improvements

[kripz]

Not sure if it's me but i just upgraded to h264enc to 9.1.5, mplayer and x264. h264enc says mencoder doesnt have h.264 support in mencoder?

compile *** DO NOT REPORT BUGS if you tweak these files ***

'make' will now compile MPlayer and 'make install' will install it.
Note: On non-Linux systems you might need to use 'gmake' instead of 'make'.

Please check mtrr settings at /proc/mtrr (see DOCS/HTML//video.html#mtrr)

NOTE: Win32 codec DLLs are not supported on your CPU (x86_64) or your
operating system (Linux). You may encounter a few files that cannot
be played due to missing open source video/audio codec support.

Check configure.log if you wonder why an autodetection failed (make sure
development headers/packages are installed).

NOTE: The --enable-* parameters unconditionally force options on, completely
skipping autodetection. This behavior is unlike what you may be used to from
autoconf-based configure scripts that can decide to override you. This greater
level of control comes at a price. You may have to provide the correct compiler
and linker flags yourself.
If you used one of these options (except --enable-gui and similar ones that
turn on internal features) and experience a compilation or linking failure,
make sure you have passed the necessary compiler/linker flags to configure.

If you suspect a bug, please read DOCS/HTML//bugreports.html.

No problems here at all with all latest versions. Do you have multiple instances of mencoder/mplayer? If so, make sure the correct one is set in the config. Also check with ldd to see if mencoder is linked against libx264 - ldd /paht/to/bin/mencoder | grep x264. Also see with mencoder -ovc help
